Excessive Daytime Sleepiness After Traumatic Brain Injury

The study aimed to identify the prevalence of excessive daytime sleepiness (EDS) in a prospectively recruited patient population with traumatic brain injury (TBI) of mixed severity. Furthermore, the study aimed to assess the relationship between patient factors and EDS. One-hundred and eighteen patients with TBI were assessed in a neurorehabilitation clinic after discharge from the emergency department. Enrolled participants were evaluated using several TBI-related outcome measures, 6–8 weeks after injury. These data represent the scores of these outcome measures. A brief description of each variable is visible in the variable view is SPSS. Furthermore, for nominal data, the label for each value can also be found in the variable view.

Using these data, it was determined that EDS (defined using the Epworth Sleepiness Scale ≥10) occurred in 48 of 118 (41.7%) patients in this study. Anxiety; depression; change in ability to work; employment status; global outcome (GOSE); social and functional outcome (RHFUQ); and symptom severity (RPCS) were associated with EDS in a univariate analysis. Anxiety was the only factor associated with EDS in the multivariate analysis (OR: 0.28 [95% CI: 0.09–0.90], P = .032).

In conclusion, EDS is common after TBI in a community setting and is associated with several factors, which likely interact to contribute toward worse outcome. Anxiety is a factor that, if routinely assessed and considered during patient care choices, may assist in favorable sleep-related outcome during and after post-TBI recovery.
